SIMATIC ET 200pro

SIMATIC ET 200pro is an especially small, extremely rugged and high-performance I/O system with IP65/66/67 degree of protection. It comprises Interface Modules to connect with PROFIBUS or PROFINET environment with standard as well as failsafe Functionality. In addition to proven wired connection you can also choose the ET 200pro IWLAN variant for wireless connection to the I/O controller. Interface modules are also available with CPU Functionality. ET 200pro is characterized by a comprehensive range of modules: power modules, digital and analogue I/O modules, motor starters and an RFID module enable the most flexible response to automation requirements. Due to its rugged design the ET200 pro can be used when mechanical load is high. Hot swapping of electronics and terminal modules during operation increases plant availability.

Design and Function

The modules of the ET 200pro usually have two or three components. Interface and power modules as well as digital and analog expansion modules comprise:

one bus connector which constitutes the backplane bus of the system

one electronics module or interface module

one connecting module

The ET 200pro Interface Modules offer flexible connection options and techniques. In addition each PROFINET Interface Module offers an integrated 2-port- Switch which enables the easy construction of line structures. In case of service, the IM can be replaced without using a programming device –the device name and parameters remain on the module. Due to the separation of mechanics and electronics, permanent wiring is possible. This permanent wiring allows exactly one electronics module to be hot-swapped in the event of a fault without having to Switch off the whole station
